Background technique
It is well known that subtropical zone weather winter is clammy, spring is moist, summer is sultry more with autumn dust, it is indoor It is such as introduced without clean with dry fresh air, no air conditioner adjusts temperature, and interior can generate moist, CO2Concentration is higher, temperature is too low Or supercooling, dust and germ are more, and because humidity leads to problems such as generation mould and peculiar smell, clothing, furniture and metope mouldy.
The method for preventing indoor moisture at present:
One is dehumidified using air conditioner dehumidification mode, and air-conditioning freeze drying causes room temperature to reduce, outdoor entrance Indoor high temperature and humidity air is easier to condense, and because the evaporating temperature of air conditioner dehumidification is relatively low or higher, dehumidifying is caused to be imitated Fruit is not significant and energy consumption is high.
Secondly, dehumidified using indoor cooled dehumidifier unit, effect is obvious but energy consumption is higher.
Above two method is all indoor air circulation passive type dehumidification mode, is not able to satisfy indoor fresh air demand, And outdoor humid air constantly enters the room, and room air is round-trip between moist and dry.
Thirdly, using fresh air dehumidifier prevent from getting damp again, but traditional fresh air dehumidifier is mainly that indoor air circulation return air removes Wet, fresh-air volume is small, and fresh air volume is unable to meet demand in most occasions, i.e., cannot be fully solved indoor CO2Content is higher to ask Topic, and air dewetting is first to freeze to humidify single processing mode afterwards, and because heat pump heating capacity is greater than refrigerating capacity, then summer dehumidifies When will increase air conditioner refrigerating load.
Four, summer using the cooling fresh air of central air-conditioning freezing water and makes fresh air dehumidification, and Summer Indoor air humidity is made to exist Within the comfort requirement of people, but this method is economically not suitable for spring fresh air dehumidification and uses.
Cold and warm air-conditioner has been widely used at present, but Conventional air conditioning units are adjusted just for entire room air Section, room air is closed cycle, does not introduce outdoor fresh air, indoor exhaust air is not discharged, oxygen in room air It is not supplemented after consumption.Especially split-type air conditioner, door and window is closed in use, and rare fresh air enters the room, long Phase, which stays in air-conditioned room, to be harmful to the health of people because anoxic leads to the symptoms such as uncomfortable in chest, mouthfeel, nausea.
Nearly zero building four seasons solve fresh air, dehumidifying and air conditioner prioritization scheme at present, are the fresh air dehumidification of higher cost Machine is combined with cooling and heating air conditioner, and there are no a kind of lower-cost four seasons to solve fresh air, the equipment of dehumidifying and air conditioner.

As indoor CO2When concentration is higher, fresh air air-valve is fully open slightly to be opened with return air air-valve:
1, heat pump is according to the size automatic running of indoor and outdoor humidity: when indoor and outdoor humidity is larger, heat pump carries out dehumidifying operation, Keep indoor humidity in comfortable range;For indoor and outdoor humidity in comfortable range, heat pump is automatically stopped operation, but heat source wind at this time Machine presses minimum air quantity operation and carries out air draft, to keep the temperature and humidity of Real-time and Dynamic Detection room air return air.
2, when equipment is run, by the driving of heat pump compressor and the conversion of four-way valve, pass through dehumidifying blower and heat source wind The driving of machine continuously carries out refrigeration to fresh air or heating is handled.Outdoor air passes through case air inlet and divides the effect of wind gusset, It is divided into two-way entrance, the first via enters fresh air air-inlet cavity, and the second tunnel enters heat source air-inlet cavity.
1., fresh air by air filter and fresh air air-valve enters pure air chamber in fresh air air-inlet cavity, then from heat exchange Device air intake surface A enters, and flows out from heat exchanger outlet air surface B and enters preheating pre-cooling chamber, is then entered by the surface air cooler that dehumidifies dry new Wind chamber, then from heat exchanger air intake surface C enter, from heat exchanger outlet air surface D outflow enter backheat return cold chamber, then by dehumidifying blower into Enter mixed wind chamber, is sent into finally by the fresh wind port of cabinet indoor.
2., the first via enter the effect that the air of fresh air air-inlet cavity is exchanged heat by heat exchanger self coupling, outdoor is come in damp and hot Air utilizes the air precooling itself to have freezed to cool down, or the air preheat heating heated using itself, i.e. fresh air are first Pre-cooling or first preheating enter back into dehumidifying surface air cooler;The air come out from dehumidifying surface air cooler, the effect to be exchanged heat by heat exchanger self coupling, The cold or heating backheat that obtains cooling down back enters back into backheat and returns cold chamber.
3., in heat source air-inlet cavity air pass sequentially through heat source surface air cooler, heat source blower, cabinet exhaust outlet send out it is outdoor.
3, equipment is according to the height automatic running of indoor and outdoor temperature: when indoor and outdoor temperature is higher, equipment is to fresh air refrigerating;Room When internal and external temperature is lower, equipment heats fresh air.
1., fresh air refrigerating when, the fresh air being first pre-chilled enters back into dehumidifying surface air cooler, is equivalent to fresh air and has obtained more systems Cooling capacity is used for dehumidification by condensation, and compared with the dehumidifying of traditional fresh air refrigerating, it is identical to be equivalent to operation of heat pump energy consumption, but its refrigerating capacity with remove Moisture increases, or same its operation of heat pump energy consumption of moisture removal reduce with it is more energy saving;Simultaneously because passing through heat exchanger dehumidifying and cooling Air obtain backheat heating, make cabinet fresh air exit surface temperature be higher than air dew point temperature without condensing, incidentally Solves the problems, such as the too low moisture condensation of traditional fresh air dehumidifier cabinet fresh air exit surface temperature.
2., fresh air heating when, into dehumidifying surface air cooler before fresh air obtain pre-heating temperature elevation, with traditional fresh air heat phase Than, dehumidifying surface air cooler condensation temperature increase, avoid winter outdoor air hot pump in low temp operation condensation temperature it is too low, lead to heat pump The low problem of heating efficiency also eliminates winter low temperature fresh air and needs the auxiliary hot preheating requirement of electricity.
3., by heat exchanger by the cold or hot progress self coupling heat exchange of heat pump itself, air conditioner outlet air and Interior Space temperature It is small to spend the temperature difference, reaches the higher purpose of air conditioning comfortableness.Because of air conditioner outlet air and the indoor air temperature temperature difference, compare conventional fan The temperature difference of coil pipe water air-conditioning is smaller, and the comfort of air conditioner is better than conventional fan coil pipe water air-conditioning.
4, equipment passes through interior CO2The height of concentration automatically controls oxygenation blower and oxygenation air-valve: when operation of heat pump, when When being sent into indoor fresh air deficiency by dehumidifying blower driving, the starting of oxygenation blower is opened with oxygenation air-valve, in pure air chamber Fresh air directly enters oxygenation chamber from oxygenation air-valve, enters mixed wind chamber by oxygenation blower, new with the drying that comes out from dehumidifying blower After wind mixing, it is sent into from cabinet fresh wind port indoor;As indoor CO2When concentration is lower, oxygenation fan parking and oxygenation air-valve are closed, Indoor fresh air is sent by dehumidifying blower driving at this time, meets the fresh requirement of room air.At this point, fresh air divide two-way from return Heat returns cold chamber and oxygenation chamber enters mixed wind chamber.
1., because fresh air refrigerating dehumidifying need the temperature of fresh air being reduced to dew-point temperature hereinafter, due to the refrigeration of equipment heat pump Amount size is certain, therefore the fresh air volume of alignment processing is then also certain, therefore fresh air divides two-way to return cold chamber and oxygenation from backheat Chamber enters mixed wind chamber, reaches that room air is fresh, the requirement without influencing operation of heat pump effect on moisture extraction.
